Overview
Salvo is a Rust web framework combining function-based handlers and tree routing with HTTP/1, HTTP/2, HTTP/3, OpenAPI, WebSockets, WebTransport, and ACME-based TLS support.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Key features
Compose endpoints from handlers and tree-based routing
Async functions become endpoints through handler macros, while the Router composes paths and middleware as a tree. Middleware follows the same handler model, simplifying route-scoped cross-cutting behavior.
Sources: [2]
Best fit
Fits Rust backends wanting API, realtime, protocol, and TLS features in one framework
It works well when REST/JSON APIs, OpenAPI, realtime connections, HTTP/3, and TLS termination need to live within a single application framework.
